Why Yoda hid?

Well shes still over 200.

What about Mace and Adi Galla?🙂

She's his foster daughter....NO! Mace isn't like that...he's noble.

So...

Well it was just a joke.

Oh.

Many Jedis are still in hiding, ( By Still, I mean the most recent books ) because they are in fear of Vader. They still hide because, they must remain cut off, they think that Vader is the new emperor

How come we never hear from them???

Because they don't want to be heard from.

That's the way it usually goes...

I still think that sooner or later in the OT, Yoda or someone could have mentioned the Jedi's hiding.

Maybe he thought they were all dead.

Actually, since it just says that in the book maybe they are all dead, according to Lucas.

Only Yoda and Obi-Wan go into hiding as they survive the Clone Wars. They hide as the Emperor is determined to wipe the Jedi from existence. Yoda isn't foolish and knows he can't fight the Empire by himself. It is all linked to when Obi-Wan tells Han "there are alternatives to fighting".

tarkin told vader "the jedi are extinct. their fire is gone out of the universe. you my friend are all that's left of their religion." this is interesting. it indicates that tarkin thinks they are gone. RELIGION?!? and SITH AND JEDI IS THE SAME RELIGION?!? well, maybe one is "a shadowy reflection of the other" (10 points if you can name where that quote is from 🙂 )

as far as yoda, it is likely that he had a "vision" of the future and knew, as dim said above, that he wasn't finished with things yet. that seems as plausible as anything.

That qoute is from Star Wars.

UBH, our thoughts on the Yoda thing are very similar. I feel the Jedi are in loads of trouble when the twins are split up at birth. Yoda and Ob1 flee w/ Luke to Dagobah. Leia is sent with Bail and the droids(and maybe Amidala) to Alderaan. Vader knows of 1 kid, so he finds them on Dagobah. But Yoda senses them coming and Ob1 flees and dumos Luke on Owen's doorstep. Yoda, diverts Vader's attention long enough for Ob1 to escape, but his wounded somehow(daekside storm?) and left for dead by Vader. He then wats for Luke to be brought for his training.

I think Vader confronts Yoda on Dagobah. They then battle on the swampy planet and Vader later knocks Yoda uncounsious and leaves thinking he is dead. What do you think about that?

I would love to see Vader fight Yoda. I just want to see Yoda fight somebody and use a lightsaber. I wonder if in the next two films Lucas will give us a reason for the darkside cave on Dagobah, I know they give one in HttE, but thats EU and not cannon. Maybe it has something to do with Vader some how becoming a Sith on Dagobah and the cave is where the "transformation" takes place.

I think Obi-wan and Yoda goes into hiding at the end of ep3, this for protecting Luke and Leia. This way they will be able to help train either of the twins in the jedi`s ways. By hiding as presumably dead they have a chance to achieve this, and as we know they did.
About the cave at Dagobah, this scene was set up by Yoda because Luke chose to bring weapons in the cave. The cave was a test of Lukes alter fear. Whiteout weapons he just have to walk through it, with weapon he will facing his fear and a possible destiny. The cave was strong with the dark force, they showed Luke that following the dark side he might as well end up as Vader did.
Luke ended up with control of his fear after this incident, as Vader points out in their confrontation on Bespin.
"Obi-wan has taught you well, I see you can control your fear"
